Abstract

A third cohort of young astronomers, who earned their PhDs around a median date of 1994 and who have recently applied for election to membership in the International Astronomical Union from the USA or for tenure-track faculty positions has been added to earlier samples, and the samples examined for demographic trends. The three groups are of similar size. The third, youngest, cohort includes more foreign-born and/or trained scientists than either of the earlier ones and more women. The median length of time from BS or BS to PhD, which had lengthened from 4 to 6 years, has apparently leveled off at 6 years. And, compared to the previous "young" sample, the present one includes many more job seekers and many fewer IAU aspirants.
